the United States, residing at Rochester,

county of Monroe, State of New York, administrators of the estate ofJOHN WAGNER, late a citizen of the United States, and a resident ofRochester, in the county of Monroe and State of New York, deceased (asby reference to the duly-certified copy of letters of administrationhereto annexed will more fully appear), do hereby declare that the saidJOHN WAGNER invented a new and useful Improvement in Folding PasteboardBoxes, of which the following is a specification.

This invention relates to folding pasteboard boxes of the type which arecommonly known as one-piece boxes. I

An object of the invention is to provide an improved hinge member for aone-piece folding box, which hinge is of such character that thematerial of the box will not break through at the hinge under ordinaryusage.

Another objectis to provide an improved box which is partly a set-up boxin character and at the same time is a folding box.

A further object is to construct a box of the indicated character sothat when the cover is folded down upon the main part of the'box, itwill maintain its closed position without the provision of any lockingmeans.

A further object is to provide an improved means for supporting andforming a backing for the hinge member of the box when the cover isclosed. 7

A still further object is to so construct the blank from which the boxis made that the backing means for the hinge member will not causebreaking or tearing of the material of the box alon the lower hingeline.

F 1g. 1 is a plan view of the enter side of the blank from which the boxof the present invention is made, after it has been completely formed.

Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1.

Fig. 3 is a perspective view of the blank after it has been set up butbefore it has been folded.

Fig. 4 is a fragmentary top plan view of been folded inwardly.

Fig. 5 is a perspective view of the box in the act of being closed.-

The present box is substantially a onethe box after the hinge supportingtabs have piece box, being formed from a single sheet of pasteboard ofrectangular form, except that it has securing means provided at the fourcorners. The blank in the first operation is cut in the form disclosedby Fig. 1 and atthe same time is creased and scored, as will bedescribed. The numeral 6 designates the receptacle portion of the blank,and- 7 designates the cover or top portion. These two sections of theblank are joined together by a hinge section 8, which hinge section isdefined by two creases 9 impressed into the pasteboard blank by a bluntinstrument so that the fibers of the pasteboard are not cut or broken,but," on the contrary, are merely compressed. This compression ofthepasteboard at thecrease lines does not weaken the pasteboard, whileallowing folding of the same along the two crease lines, so that thecover may enclose the box. The provision of these crease lines is one ofthe important features of the present invention; g

, The section 6 of the box is'provided with an end flap or flange 13 anda pair of side fiaps'or flanges 15, all three flaps being defined byscore lines 14. These score lines are made by a-knife-like instrumentwhich cuts into the material ofthe blank so thatwhen the flaps arefolded and the box is set up, the

'. other and. with the ends of the hinge section 8. In order to give thecover sufficient dimensions to enclose the receptacle portion of thebox, there is a continuous taper from,

the flap 13 to the flap 12 along the score lines 10 and 14. In otherwords, the ends of the score lines 10 adjacent the flap 12 are fartherapart from each other than are the ends of the score lines 14 adjacentthe flap 13. This taper in a box of the size and character indicated inthe drawing may be one sixteenth of an inch.

After the blank has been cut in the manner illustrated in Figs. 1 and 2,the box is set up by a well known type of machine, this setting upprocess consisting in bending the flaps 11, 12, 13, and 14, at rightangles to the main body of the blank so as to stand. up in the positionillustrated in Fig. 3. hen the flaps are in this position, bindingelements 18 are applied by machinery, whereupon the abutted end edges ofthe flaps are united together. The box is now complete except for thefolding.

The flaps 15 have at those ends nearest hinge section 8, tabs 16, whichtabs are separated from the flaps 15 by score lines 19. Each tab 16 isseparated from the hinge section 8 by a narrow \l-shaped cut 17, andthis cut extends to the score line 19. The score lines 19 are offsetfrom the adjacent crease line 9 by a distance which may ap-. proximateone sixteenth of an inch. The cut 17, therefore, extends past the creaseline 9 and separates the crease line from the score lines. The effect ofthis construction is that any tendency on the part of the tabs to splitalon the score line 19 is not communicated aong the adjacent crease line9. This construction is another important feature of the presentinvention.

With the box in the condition illustrated in Fig. 3, all that isnecessary to do is to fold the tabs 16 inwardly, as illustrated in Fig.4, whereupon the material of the box will break along the score lines 19sufliciently so that the said tabs will remain in their folded position.Then the cover"? of the box is brought over into closing position asindicated in Fig. 5, whereupon the material of the box will fold alongthe two crease lines 9 and the cover may be brought all the way over soas to completely house the receptacle section of the box. The taperingof the score lines gives the cover section of the box sufiicientdimensions so that this enclosing may take place. As will be seen fromFig. 5, the inturned tabs 16 serve as a backing for the hinge section 8as the cover 1s brought down upon and closed over the receptacle.

The box of the present invention is described and claimed as though itwere not covered with a paper wrapper. In actual practice, boxes of thistype are very commonly provided with such a wrapper,

which is usually colored and printed with advertising matter. A wrapperdesigned especially for the present box is described and claimed in anapplication filed by Herbert H. Wagner, on October 23 1920, Serial No.418,881. The process of uniting the present box with the improvedwrapper is covered in Patent No. 1,363,024, dated December 21, 1920. Themeans for holding the pasteboard box during the uniting thereof with thewrapper is described'and claimed in Patent No. 1,363,025, dated December21, 1920.

The present application is a continuation in part of an applicationfiled August 15, 1918, Serial No. 249,998.

What is claimed is 1. A blank for making a one-piece folding pasteboardbox comprising a cover section, a receptacle section, and a hingesection joining the other two sections, all three sections beingsubstantially rectangular; the

cover and receptacle sections both having integral flanges on threesides thereof separated therefrom by score lines, the score linesextending longitudinally of the blank converging slightly and uniformlyfrom the cover end of the blank to the receptacle end whereby the coverhas sufficient width when the box is folded to enclose the receptacle.

2. A blank for making one-piece folding pasteboard boxes, comprising acover section, a receptacle section, and a hinge section intermediatethe other two sections and connected with each by a crease line, whichcrease lines ar substantially parallel to each other, said receptaclesection having side flanges and each side flange having a tab integraltherewith at the end thereof adjacent the hinge sect-ion, each tab beingseparated from its flange by a score line, and the score line of eachtab being offset from the nearer crease line, said tab being separatedfrom the hinge section by a narrow V-shaped out, which extends past thenearer crease line and separates the crease line from the score line,whereby the tendency on the part of the tab to split along the, scoreline is not communicated to the adjacent crease line.

3. A blank for making one-piece folding pasteboard boxes including areceptacle section, a cover section, and a hinge section cut into, saidtabs extending from the ends of the flanges to which they are attachedtoward the opposite ends of the side flanges of the cover section beforethe box is set up and folded, a cut-out portion in the blank spacingeach tab from the hinge section as well as from the side flanges of thecover, the cut extending past the hinge line and separating the hingeline from the score line of the tab, the score lines of the tabs beingoffset from the nearer hinge line and in alinement with each other.

4. A folding pasteboard box comprising a cover section, a receptaclesection, and a hinge section intermediate the other two sections joinedto the same by parallel crease lines, both the cover section andreceptacle section having side and end flanges adapted to be set upprior to the folding of the box, said cover section being of suflicientdimensions to enclose the receptacle section when the box is folded,tabs provided on the side flanges of the receptacle section and havingscore lines by which they are adapted to be bent inwardly relative tothe box, said score lines being offset from the nearer crease line, saidtabs together providing a backing for the hinge section when the box isfolded, each tab having its lower edge inclined and spaced above thebottom of the receptacle with said space increasing as the end of thetab is approached, and with said lower edge separating the nearer creaseline from the score line of the tab, the upper edge of the tab beingcontinuous with the upper edge of the adjacent side flange of thereceptacle.

5. A folding pasteboard box comprising a cover section, a receptaclesection, and a hinge section intermediat the other two sections, thematerial of the blank which forms the box being creased in two lines toform the hinge section, said creases compressing the blank withoutcutting the fibers thereof, both the cover section and receptaclesection having side and end flanges adapted to be set up prior to thefolding of the box, said cover section being of sufficient dimensions toenclose the receptacle section when the box is folded, tabs provided onthe side flanges of thereceptacle section and adapted to be bentinwardly relative to the box, the tabs being defined by score linescutting into the material of the box, said score lines being offset fromthe crease line which joins the hinge section and 'the receptaclesection, said tabs together providing a backing for the hinge sectionwhen the box is folded, each tab having its lower edge spaced above thebottom of the receptacle with said space increasing as the end of thetab is approached, th upper edge of the tab being continuous with theupper edge of the adj acent side flange of the receptacle.

In testimony, that we claim the foregoing as the invention of JOHNWAGNER, we have hereto aflixed our signatures in the presence of twowitnesses.
